This comment "..weld on attachment
technique provides 12 square inches of area..." refers to the outer perimeter of the mounting plate. I believe my use of terminology is correct, as noted by mangler.
Yes, I also agree that a solid weld on brace IS superior to any bolt-on arrangement. That's why the brace in my car is done accordingly. However, a quick campus of our customers told me that the prevailing preferred mounting arrangement is by bolt on. Therefore, in the interest of appealing to the largest possible denomination I designed a brace that could be mounted in either fashion.
